What is the "Beat Method" for Inspecting an Oscilloscope’s Time Base Accuracy?

In the oscilloscope's QIS (Quality Inspection Standards), the "beat method" can be used to inspect and verify the time base accuracy. The "beat method" utilizes the aliasing effect to create a "beat waveform." The "beat waveform" has a frequency that is compared to the specfication of the oscilloscopes time base accuracy. For more information, please download and view the PowerPoint presentation "Oscilloscope's Time Base accuracy inspection by beat method."
